Thats a real smart teacher, they should appreciate that he is not feeding them BS but real documented FACTS AN KNOWLEDGE. btw the theory is called Mitochondrial Eve. #Love it!  

Happy Earth Day!

It’s Earth Day, and what better way to celebrate than to show you a glimpse of our various efforts to protect and understand our home planet.

We’re able to use the vantage point of space to improve our understanding of the most complex planet we’ve seen yet…EARTH! Our Earth-observing satellites, airborne research and field campaigns are designed to observe our planet’s dynamic systems – oceans, ice sheets, forests and atmosphere – and improve our ability to understand how our planet is changing.

Here are a few of our Earth campaigns that you should know about:

KORUS-AQ (Korea U.S. - Air Quality)

Our KORUS-AQ airborne science experiment taking to the field in South Korea is part of a long-term, international project to take air quality observations from space to the next level and better inform decisions on how to protect the air we breathe. Field missions like KORUS-AQ provide opportunities to test and improve the instruments using simulators that measure above and below aircraft, while helping to infer what people breathe at the surface.

This campaign will assess air quality across urban, rural and coastal South Korea using observations from aircraft, ground sites, ships and satellites to test air quality models and remote sensing methods.

NAAMES (North Atlantic Aerosols and Marine Ecosystems Study)

Our NAAMES study takes to the sea and air in order to study how the world’s largest plankton bloom gives rise to small organic particles that influence clouds and climate. This study will collect data during ship and aircraft measurement campaigns and combine the data with continuous satellite and ocean sensor readings.


Operation IceBridge is our survey of polar ice, and is kicking off its eighth spring Arctic campaign. This mission has gathered large volumes of data on changes in the elevation of the ice sheet and its internal structure. It’s readings of the thickness of sea ice and its snow cover have helped scientists improve forecasts for the summer melt season and have enhanced the understanding of variations in ice thickness distribution from year to year.

GPM (Global Precipitation Measurement)

GPM is an international satellite mission to provide next-generation observations of rain and snow worldwide every three hours. We launched this mission with the Japanese Aerospace Exploration Agency (JAXA) in 2014. GPM contributes to advancing our understanding of Earth’s water and energy cycles, improves forecasting of extreme events and extends current capabilities of using satellite precipitation information to directly benefit society.

I often think of that study about stereotypes, wherein children are asked to draw a scientist, and they almost unilaterally draw a bearded white man.

I think if you asked most children to “Draw a Farmer,” you would by-and-large get the same result.

It’s odd, because globally, women are about half of the formal agricultural workforce, and we produce (and cook!) the majority of the world’s food.

I remember my grandmother had a vegetable garden that was about half an acre large. She produced, canned, and prepared the vegetables the family actually ate, whereas my grandfather farmed barley and wheat and took care of the animals. They were both doing intensive agricultural labour, but the difference is he had the chance and to earn money for his work. It’s more than a mere division of labour: it’s a division of capital and freedom that squarely favoured my grandfather. He was “the farmer,” and she was “the farmer’s wife.”

That historical barrier between informal and formal work–and the perceptions of the relative value of both–is a huge part of why women are lagging far behind in factors like property and equipment ownership.
